Five Islamist extremists burst into the church of Our Lady of Salvation in Baghdad in October, murdering two priests, holding the congregation hostage and eventually killing more than 50 people. Now Amnesty International has warned of a spike in violence in the run-up to Christmas and has urged the Iraqi government to do more to protect Christians, who are now believed to number less than 500,000, about half its level of seven years ago.

Only 40 people turned up for mass at Our Lady last Sunday. They sang and chanted, a forlorn gathering of survivors, the walls around them spattered with blood and cratered by bullet-holes. The bloodied hand prints of those who failed to escape marked the door in an ante-room.
